Method for intercropping and cultivating konjak by northern high-stem plant

Abstract

The present invention provides a method for intercropping and cultivating konjak by a northern high-stem plant, which is characterized by comprising the following steps: A, intercropping and cultivating the konjak in a forest land or a corn field, applying 1 to 2 tons of decomposed organic fertilizer for each mu, then spreading 100 jins of calcined lime over each mu to sterilize the soil, and turning over and flattening the field; B, sterilizing konjak seeds; C, adopting ridge culture and oblique culture to intercrop 3 to 5 rows of konjak at a konjak ridge height of 20 to 30 centimeters, a ridge surface width of 20 to 25 centimeters and a forest belt of 3 to 5 meters, or intercropping 1 to 2 rows of konjak in a corn row, and inclining the seeds for 45 degrees facing the sun; and D, performing grading seeding, wherein the planting density uses 6 to 8 times diameter of the konjak seed as a row space and 4 to 5 times diameter of the konjak seed as a plant space, and covers 15 to 20 centimeters of soil. By adopting the technical scheme of the present invention, the increment amplitude of intercropping the konjak in the forest land is 3 to 7 times that of the primary seeds, the per mu yield reaches more than 1,500 kilograms, the utilization efficiency of the forest land is improved by over 20 percent, the economic benefit in each mu is increased by more than 2,000 yuan, and the utilization path of the forest land is effectively broadened.

Description

technical field

[0001] The invention relates to a method for intercropping and cultivating konjac with tall stalk plants in the north, belongs to the technical field of plant cultivation methods, and is especially suitable for intercropping and cultivating konjac in northern woodlands or corn fields. Background technique

[0002] Konjac bulbs contain high organic glucomannan, which is a kind of soluble semi-fiber, which has the properties of gelling, gelling, etc. and significant effects of losing weight, reducing fat, and lowering blood sugar. It can be used in the food industry, chemical industry, and pharmaceutical industry. , agriculture, environmental protection and other fields, as the value of konjac products is increasingly valued by the market, konjac planting has been carried out on a large scale in the Yangtze River Basin. With the increasing demand for konjac, the konjac planted in the south can no longer satisfy the market. However, due to factors such as slow nat...
